Continuity mistake: Robin calls up Cyborg as he makes his way to Steel City. When we see Cyborg on screen, the sky is daylight-blue and a bit cloudy. When Cyborg is seen personally, however, it is night outside  i.e. a dark clear sky full with stars; and when he activates the T-Car's hover function, it is still night, but the starry sky has suddenly become heavily clouded.

Continuity mistake: Steamroller has two hands encased in cone-shaped gauntlets, but whenever he puts them together to pin someone down, the gauntlets assume a cylindrical shape. It happens every time we see this character in action throughout the show.

X-X "The Lost Episode": Some other character cameos in the concerto audience include the two English ladies talking about fish in "Revolution", and Dr. Victor Payten, his interviewer, and the soap opera character Rebecca from "Episode 257-494".
